Y CAR-DOOR LOCK.

Application filed May '10, 1923. Serial lilo. 638,136.

1' 0 aZZ whom it may concern.

Be it known that I, PETER F. OCoNNon, a citizen of the United States, residing at La Salle, in the county of La Salle and State of Illinois, have invented certain new and useful Improvements in Car-Door Locks, of which the following is a specification.

This invention relates to an improved car door lock and seeks, among other objects, to provide a simple and efficient device of this character for effectually securing the door of a car closed.

The invention seeks, as a further object, to provide a device embodying a rotatable bolt to coact with the hasp employed and wherein, when the bolt is rotatably advanced to engage through the hasp, the bolt will coact with the hasp for drawing the door tightly closed.

And the invention seeks, as a still further object, to provide a device which may be readily applied and which may be used in connection with conventional railway car doors without the necessity for structural change therein.

Other and incidental objects will appear hereinafter.

In the drawings: v

Figure 1 is a fragmentary side elevation showing my improved lock applied,

Figure 2 is a horizontal sectional View on the line 22 of Figure 1, looking in the direction of the arrows,

Figure 3 is a vertical sectional view on the line 33 of Figure 1, looking in the direction of the arrows, and

Figure 4 is a detail sectional view on the line e4 of Figure 1, looking in the direction of the arrows.

In carrying the invention into effect, I employ a hasp 10 which is formed near its inner end to receive a bolt or other suitable fastening device 11 connecting the hasp with a car door, as conventionally illustrated at 12. The door is of the usual sliding type and is shown in conjunction with an ordinary door jainb 13. Near its outer end, the hasp 10 is offset and is formed with an eye 14 lying at substantially right angles to the plane of the inner end portion of the hasp. The eye is provided with flat parallel sides and with a rounded inner edge 1.5 while from the forward edge of the eye projects a forwardly directed thumb lug 16. Preferably, the hasp is flattened at the 0H- set therein to produce the eye and in thus flattening the hasp, a thickened shank 17 15 formed, this shank gradually tapering toward the eye and being braced at its outer edge by a reinforcing rib 18 lying in the angle between the inner end por'- tion ofthe hasp and the eye. The eye will thus be rigidly sustained while the likelihood of the eye becoming broken'off at the shank will be reduced to a minimum.

Associated with the hasp is a keeper enibodying a body block 19 provided at its ends with oppositely directed flanges 20 which are formed to receive bolts or other suitable fastening devices connecting the keeper with the door jamb. The block is provided near its lower end with ajtransverse slot 21 defining a lug 22 beneath the slot and formed in said lug from the upper side thereof is a socket 23 from which leads an axially disposed drain passage 24 opening downwardly through the lug. Threaded through the block 19 from the upper end cylindrical recess 28 and intersectingsaid.

recess, are, as shown in detail in Figure 4. registering openings 29. Rising from the block to surround the recess 28 is an annular flange 30 and removably threaded upon said flange is a closure cap 31.

In conjunction with the look, I provide a key 32 which, as shown in Figure 3, is formed with a socket 33 adapted to fit over the head 26 of the bolt 25 within the recess 28 of the block 19 of the keeper. Thus, after the car door 12 has been closed to project the eye 1d of the hasp lO'through the slot 21 of the keeper, the key 32 may be engaged with the bolt head and turned for rotatably advancing the bolt and engaging the tapered end portion 27 thereof through the eye of the hasp. As the bolt is thus advanced to seat the lower end of the tapered portion 27 thereof in the socket 23, said tapered portion of the bolt will, as will. be seen, coact with the wall of the opening in the eye 1 1 for drawing the hasp forward and binding the. door tightly closed and locking the door in closed position. As will be observed, the rounded inner edge of the eye seats flat against the inner wall of the slot- 21, which wall is rounded to fit the inner edge of the eye, so that as the hasp is thus wedged forwardly, the edge 15 will ride over the inner wall of the slot for sustaining the eye against inward thrust while, when the hasp is at rest, said wall or slot will provide an abutment for the eye, The wire of a seal, conventionally illustrated in Figure 1 of the drawings at 34-, may then be inserted through the openings 29 to extend across the recess 28 above the bolt head 26, for preventing unauthorized unlocking of the door, whenthe cap applied for excluding dirt and moisture.

Formed on the bolt head 26 are one or more radial lugs and formed on the flange 30 at its inner side are substantially semi-circular stop shoulders 36 to coact with said lugs for limiting the bolt against accidental upward displacement. l iiowever, sh uld ii; be found necessary to remove the bolt, the bolt may be turned to dispose the lugs 3 in register with the spaces between the ends of said shoulders when the bolt be connection to a car door and provided with an eye, a keeper block for connection to the door jarnb, a removable bolt rotatably ad justable upon the block to engage through the eye of the hasp, and means limiting the bolt against accidental displacement.

3. A car door lock including a hasp for connection to a car door and provided with an eye, a keeper block for connection to the door jainb, and a bolt rotatably adjustable upon the block and provided with a tapered end portion to engage through said wedging the door closed.

4:. A car door lock including a hasp for connection to a car door and provided with an eye, a keeper block for connection to the doorjamb, a bolt rotatably adjustable upon the block to engage through said eye and provided with a head, the block being formed with a recess to freely accommodate the head of the bolt, and a cap normally closing said recess housing the bolt.

5. A car door lock including a hasp for connection to a car door and provided with an eye, a keeper block for connection to the door jamb, a bolt rotatably adjustable upon the block to engage through the eye of the beep and provided with a lug, and spaced shoulders on the block disposed for engagement by said lug for limiting the bolt against accidental displacement, the bolt be ing movable to a position whereby said lug may pass between said shoulders and thrbolt removed.

In testimony whereof I atiix my signature.
